Splicing into 14-3 for smoke detector

I live in a 6 year old house and want to add a gable attic fan. I can't get a 14-2 line to the panel box for a dedicated circuit. My question is, my smoke detectors (5 of them) are on a dedicated 15amp breaker. I can get the 14-2 in one of the smoke detector's with two 14-3's in it. Would I just hook up black to black and white to white? Since the red is more than likely the traveler.

Any input and/or suggestions would be great.

Where are you located ?

Are smokes required to be on a dedicated circuit where you are ?

Virginia. Not Sure on code, everything that I have found just says that need to be hard-wired and battery backup

I'm not an electrician, but I did spend 25 years in the fire service, (and I stayed at a Holiday Inn Express once). Even though it would probably work, I would try and tie into something else besides the smoke detectors. Even with a battery backup, I wouldn't want to chance the attic fan tripping a breaker and leaving you just on the batteries. Smoke detectors are cheap insurance and will buy you a little time to get out of the house if something happens. You want to give them the best shot at working. People forget to change batteries, especially when they are hard wired, so you could end up with just enough juice in them to keep them from chirping, and then if needed, would die out quickly. Just my .02, better to be safe.

I agree attic fan and smoke detector on the same circut sounds like a bad idea.

not an electrician, firemen or frequent Holiday Inn Express customer, but....

Just a wild guess here, but I bet attic fans are fairly high up in the list for causes for electrical fires. They operate in a hot environment, no drywall to act as a fire barrier, they often get wet, they often have rodent encounters and they are "out of sight / out of mind".
